hello ccf its been a heck of a ride untill now. I'm still going tru some suspicious coins I have, or atleast I think they are. so as the knowledge grows little by little, I'm getting more and more eye for the unusual stuff. so I have this 4 reales coin that exibits some strange blotches. the kind that you c on cast contemporary counterfits. althought the coin specs are within limits there still some weird things going on,on the coins surface. nway some info silver 0.925 13.3 grams 32 mm aprox 1.9 mm thickness     blotches I mentioned   so now comes the million dollar question..... is this genuine or not? please share your opinions P.S still have't bought a 0.01 scale so specific density is something I can not provide at this point in time. |

What does the coin ring test tell you? Compare the ring to a Morgan dollar. Identical in pitch? JPL |

i hate to say it but I don't own a Morgan dollar ....yet ,to scared to buy fakes so I took it out of his 2x2 and spinned it on my desk; it gave a high pitch while turnnig i also tryed to ping it a few other ways I'm just not shure what sound I'm looking for because purity and shape can realy make a diffrent sound I've read also because that is the first time I was askt do do a ping test. so I did compare it against a little smaller coin with a 0.8350 purity and a 2013 eagle walking liberty dollar the pitch was a litlle lower and the eagle had the highest pitch of them all thanks JPL Edited by dohcollector

@dohcollector, I generally lurk on the threads that discuss real vs. fake, as others here are much more knowledgeable.
However, I'd like to point something out to you while we wait for the experts to weigh in. It seems like some of the flat fields on your coin (especially on the obv) have irregular raised bumps on them. To me that is quite concerning as I don't think that can happen with a struck coin.

spence thanks for comming in
thats is actually the reason why I am here asking ,but I had so many views and no repley's that I started a more thurrow search on my own.
so I started looking and found out these coins also have described dies,witch I did not know
but I lack that resource
after comparing some of'm I noticed it could be the same die or it is the same coin but a duplicate of that coin.
atleast that is in my opinion
if its the right one remains to be seen :)

Yes no prob. As you know, there are several folks who really know their stuff, but hopefully SwamperBob will offer his opinion on your coin.

Gas Bubbles http://www.error-ref.com/?s=gas+bubblesThe raised metal dots throughout is normally a sign of the die transfer process used currently by present day Chinese counterfeiters which I describe in my upcoming book and is common knowledge for serious collectors who purchase real contemporary circulating counterfeits like myself today. I did not mention this earlier as sometimes its difficult just to make definitive conclusions with just a photo without actual testing. I usually leave this to Gurney who likes to plate match and perform detailed analysis on photos. I am lazier and strictly use scientific instruments. LOL. Be that as it may ... Note also on Chinese counterfeits we usually see a Plain Edge or a recent milled edge which appears like it was made last week. Since your edge appears regal this may be a more sophisticated die transfer casting fake? The ring test did exhibit a lower pitch as 90% Ag always ring test higher than Fe/Ni, German Silver (Cu/Zn/Ni) and of course a debased silver issue normally with copper. If you look at the U.S. Federal Error Coin website developed by Weinberg/Sullivan/etc. above you see occluded gas bubbles when they do appear are normally on a plated coin like the current copper plated Zn cents in the U.S.. So based on its lower ring pitch ring test, probable die transfer casting bubbles its probably a well made fake. Never BUY a coin with these raised metal occlusions - IMO. Never ... Sure another interesting coin to perform SEM/EDS and XRF analysis on in my lab ... JPL |

The coin is too crude to be real even just by basic instinct. Even if the weight is correct and it is made of silver, it is still fake to me.

With just pictures its USUALLY difficult to reach a better conclusion.
With these surfaces and lower coin ring its SUSPICIOUS.

thats ok colonialjohn I just wanted to give a more indepth view of the surface, did not know you could not make up more out of them
guess I read the original repley wrong I thought there was a diffrence in gas bubbles and plating but after rereading I could c the mistake
sometimes my englisch is't all that
again thanks for the assistance
